Default Hair of the Dog - Stuck Fermentation

Brewed a Hair of the Dog - Adam clone
a big beer supposed to start at 1.094 and finish at 1.020

- started 1.105 - used a 2 L starter
had an intense fermentation of about 4 days
finished 1.055

added oak and cherries - thought the fruit might help kick up fermentation
shook the carboys

after a couple of weeks - I transferred to new carboys
- added a 2 L starter of champagne yeast
had a flimsey fermentation down to 1.050

all using my refractometer

Not sure if I should try to start again - maybe a bigger starter ? or just keg it and drink it !
Cheers

I've heard that the best way to kick start a stuck fermentation is to make a new starter and pitch at high krausen. Looks like you underpitched to begin with....

What was your grain bill if you had a lot of unfermentables there maybe an issue with the recipe not the fermentation

Try taking a reading using your hydrometer and your refractometer and see if they agree. From what I've read the refractometer have trouble giving an accurate reading with high alcohol.

I used the White labs equivalent and made a 2 L starter of the 2 together
Seems like I should make a bigger starter?
I did get a massive fermentation though , blew the tops off

Holy cow, 50 lbs of pale malt for a 10 gal batch, so you scaled down to 5 gal and used 25 lbs? Plus your other grains. That's monsterous.

I have no idea what size starter you would need, at least a 1 gal if you ask me. I probably would've stepped up a few 1ish L starters until I got to 1 gal.

I definitely agree with taking a hydrometer reading instead of refractometer. Don't use your refractometer to take readings once fermentation has begun, it gets screwy.

You still have a fairly big beer there, so don't sweat it too much. Maybe let it sit for another few weeks to see if it comes down anymore, and then keg/bottle it!

Yup I did that - made another 2 L starter w champagne yeast (guys at the shop said this would be better for high gravity)
It started fermenting but not very strongly went from 1.055 to 1.050
Maybe I should do it again but step it up?
